Subject: The Novel Technology of Odor Removal in High-tech Factory and Its Practical Application
Abstract
In the process of the photovoltaic industry, the wastewater containing sulfur-containing organic solvents such as dimethyl sulfoxide (Dimethyl Sulfoxide, DMSO) is easily reduced to odorous substances such as dimethyl sulfide (DMS) and hydrogen sulfide (H2S) under anaerobic conditions. Chlorine dioxide (ClO2) is internationally recognized as a new generation of high-efficiency disinfectants and oxidants. The chlorine dioxide can completely oxidize the odorous substances such as DMS, H2S, and mercaptan to odorless products. The novel technology is to apply the high-gravity chlorine dioxide gas generator to produce stable, fast and safe chlorine dioxide gas on site which can avoid the shipping or storage problems and has low operating cost. A large-scale photovoltaic factory in Taiwan has applied this technology to treat the exhaust gas from the wastewater treatment plant. The exhaust gas contains obvious odors resulted from DMS and H2S. The ClO2 gas produced by this technology is introduced into the existing exhaust gas line. As a result, it has been confirmed that the reduced sulfur compounds in the exhaust gas have not been detected.
